Title: Basic Concepts Of Bitcoin Mixers
Post by: Tribalchief on April 20, 2024, 03:44:15 PM
Introduction
As more mixing services become available in the Altcointalks community, it's important that everyone who comes across them genuinely has a basic knowledge of what they do. Understanding the entire concept of how mixing works might not be too necessary for everyone, especially when we are not the ones offering the service. However, with just a basic knowledge about them, everyone would understand their importance to cryptocurrency in general. This post provides basic knowledge only and does not go in details.

What's a Bitcoin mixer ?
Bitcoin mixers, also known as Bitcoin tumblers, are software or services that let users mix their coins with other users in order to further increase the privacy of their Bitcoin transactions. Bitcoin was the first cryptocurrency to use the tumbling service, though other cryptocurrency can use a tumbler.

Ideally, Bitcoin addresses are partially anonymous, which means they don't directly reveal the identity of their owner, but they can still be linked to real-world identities.



The Blockchain, which happens to be a public record of Bitcoin transactions, contains every stamped, dated, and transferred transaction that is stored. Any transaction on almost all blockchains is public, which means you can easily see and track where all the money is going.

The ability to view one's wallet address and see where money is coming from and going to is a big privacy risk for individuals. The purpose of a tumbler is to create privacy around the cryptocurrency that you own.

In recent times, some have argued that mixing and tumbling are two different terms. They propose that Bitcoin tumblers are services that mix coins from multiple users, while Bitcoin mixers are services that break up the transaction history of Bitcoin. Whichever concept is aligned, the main purpose is to provide anonymity to those who use it.

Types of Bitcoin Mixers

Centralized Mixers: are Third-party mixers that accept Bitcoin payments, mix them with other Bitcoins and send the equivalent amount to the required address for a fee.

Decentralized Mixers: are Mixer services that utilize open-source protocols, such as Coinjoin, combine Bitcoin into a single large transaction and redistribute it to the destination address. This process is similar to centralized methods, but it's automated and doesn't involve third parties.

Note that the most popular mixing services are currently centralized.

Why would you want to mix your coin?
Financial privacy is a key concern for both users and non-users of cryptocurrency. Traditional financial institutions such as banks do not provide this level of privacy, as they can disclose information to law enforcement agencies or governments at any time. When it comes to mixers, the guarantee of your privacy depends on which mixing service you use.

How do I identify a Good mixing service?
This happens to be a critical part that everyone must take seriously. The internet is currently flooded with lots of false mixers that use links similar to true mixers. These false mixers sometimes design their platforms to mimic the original in order to lure people.

When choosing a mixer, it is required that everyone conducts proper research on how long the particular mixer has been operating. Try to find out from others who have had personal experience (though don't believe everything), and start by mixing smaller amounts (which is where the risk comes in).

Note: Coinjoin as mentioned above, according to investopedia.com is an anonymization strategy that protects the privacy of Bitcoin users when they conduct transactions with each other, obscuring the sources and destinations of BTC used in transactions.

Information: This post provides basic knowledge about Mixer and nothing more. Choosing to use any of their services after reading this post is at your own discretion. .

This is a very good post, especially for people who do not know how mixers work. I know the government and centralized institutions are against privacy solutions, but BTC users must understand how important privacy is in the network and using mixers is a good way to enhance your privacy.

Some people even believe that you need to have something to hide before you use mixers, which is so wrong. Unijoin, which is a recommended mixer posted an article on this some weeks ago, and it is a good read for those who are interested:

Nice guide by the way op. At least for those who doesn't know what Tumblers are, can start from here.

They are generally known as tumblers. They're designed to enhance Bitcoin privacy. Whether you call them mixer or a tumbler, they're the same thing. Like you said, most mixing services today are centralized, meaning they're controlled by a single entity and third parties. Only a few, like CoinJoin, operate in a decentralized manner. When using a mixing service be aware that centralized mixers have full control over your coins during the process. So, it's important to research and choose reputable services to avoid the risk of losing coins. Many new mixers are entering the market, but most of them are scams or have ulterior motives. Remember, while increasing your privacy, you should also be smart enough to protect your coins too.

Since this thread aimed for beginner, i believe we should mention that some exchange and services reject mixed coin due to various reason. If you still deposit or send your coin to them, usually your account would be frozen and they'll ask for tons of personal information if you want to get your coin back.

I don't know about other people, but personally i don't consider CoinJoin as part of mixer. In past, it's rare to see people use term mixer/mixing/mix when describing CoinJoin. Mixer break transaction history, while CoinJoin usually obfuscate it.

It's high time we start erasing all misleading information about mixers and other crypto related matters. Privacy matters alot especially for those that have choosing to make crypto part of their lives.

In as much as we want to protect our financial privacy, we must also be careful with what service we choose to use, because no scam service would return funds after they've scammed their victims. But interestingly, we still have reputable mixers everywhere.

I don't know about other people, but personally i don't consider CoinJoin as part of mixer. In past, it's rare to see people use term mixer/mixing/mix when describing CoinJoin. Mixer break transaction history, while CoinJoin usually obfuscate it.

In as much as I don't want to mention a specific mixing service, the word Coinjoin used in this context isn't relating to a service either. Here is what I meant..

Unijoin is a mixer, but it uses the CoinJoin technology. Coinjoin protocols are self custodial and trustless, i.e. WabiSabi, JoinMarket and Whirpool, people who use these protocol remain in control of their funds. Unlike mixers that you have to deposit coins into the address specified by the mixer. This is the big difference between CoinJoin implementations and mixers.

If you look at the functionality of the Coinjoin method, it has the basic characteristics of mixing. The user sends his Bitcoins with the aim of receiving completely different ones, I would call such a process mixing.
Efficiency is another matter entirely.

~snip~


There is some truth in that, but still from my own experience it doesn't happen often, at least it never happened to me that someone had a problem because I sent them coins that have their origins in mixers. By that I mean transactions that went from my non-custodial wallet to CEX addresses, but also those transactions that went through payment processors.

Maybe there should be some imagination in all of this, and the already mixed coins should be "stirred" a little more in such a way that we move them several more times to new wallets. Thus, we can make it difficult for those who analyze the blockchain to determine where exactly the coins came from, and the question always arises as to how deep they go with their analyses.

i never had problems as well, but i know some people already had problems.

I usually consolidate my coins from mixers and split them in different addresses, so I usually never send directly from mixers (or from campaigns) to an exchange.

@bitmover, maybe there is more deception than truth, because considering how big a problem mixers have become for "them", I would not be surprised that most of the problems with mixed coins actually originate from the propaganda war waged by these very same people. They may be solving part of the problem by discouraging people from using any private tools, including mixers, by scaring them that something bad will happen to them.

Likewise, more or less all CEXs do not want coins related to gambling, but people still gamble even more than before using cryptocurrencies.

I agree. I do the same with coins I receive from casinos. I received a lot of coins from casinos, and also never had problems using them in cex. I also did the consolidation/split in some addresses with them...

There is also Joinmarket that is better option than Coinjoin and it is fully decentralized.
I would also add coins that have integrated ''mixer'' in them, for example Monero, that is super easy to use and it's decentralized, that is why regulators don't like it very much ;)
I wish something like this can be added to Bitcoin code, maybe with MimbleWimble like in Litecoin.

That's true, i mentioned that since it's possible some beginner except they won't face any trouble by using mixer or coinjoin. And it heavily depends on which mixer/coinjoin and exchange they use.

It sounds like exchange you used doesn't perform detailed blockchain analysis, which is good for you.

But with how Bitcoin community/devs value backward compatibility, it'll be optional privacy feature and those who use it obtain less privacy due to small amount of Bitcoiner who use it.

There are many investors in bitcoins who know nothing about mixers and the services they provide. They are okay with just the anonymity that bitcoin provides, and because they have not been involved in anything illegal, they have had no reason to be concerned about their privacy.

It is not a must for every investor to use mixers.

*not anonymity

Let's not kid ourselves here, Bitcoin is not *anonymous* like Monero is. It is at best pseudonymous, otherwise we would not have to worry about all these blockchain analysis scrapers compiling data about our transactions.

Mixing bitcoins does not make them anonymous either, it just makes them a little more pseudonymous. It is a limitation of the Bitcoin protocol.

"Illegal" with every mention of mixers or similar series is the narrative that governments want to impose. Under this pretext, services that offer more privacy are closed and confiscated. It is indeed about the desire for greater control of people and better insight into their privacy.

I have also send coins straight from exch.cx to a local exchange here in Brazil (Foxbit) and binance as well. Never had problems...

Fortunately for all of us, Bitcoin is not anonymous in the true sense of the word, because the question is whether it would be at this level of recognition and "permission" today. It's no secret that practically from the earliest days, the world's most powerful three-letter agencies have been working on user identification and transaction methods - and they certainly don't do that because they're bored in life.

Bitcoin has become a threat since the Genesis block, but with time the idea of cryptocurrency is being suppressed, and the idea of digital gold and trading through futures & spot ETFs and through CEXs enables more and more control over those who use it.

Mixing bitcoins does not make them anonymous either, it just makes them a little more pseudonymous. It is a limitation of the Bitcoin protocol.

That's right, we also had the opportunity to see it on concrete examples of someone who posted a topic on BTT about how he managed to break some mixers, although all but CM at that time. Has anything changed today in the way mixers work - probably not much, but as I already wrote, a little imagination after mixing can make things more complicated for those who analyze the blockchain.

If you're a bitcoiner and have the intention of making huge bitcoin transaction from one wallet to another, the you may have to make use of a bitcoin mixer, the reason for this is on privacy, you will not have to pass through the use of an exchange or make your transactions open to the public so that they don't know about what you're up to, with this, you can make use of a mixer, its affordable to use and reliable in most cases, we have the likes of coinomize.biz among others to render the required service needed.

I wouldn't say that Bitcoin provides complete anonymity for its users, though I agree with the fact that most people in the crypto space are completely fine with the protocols of Bitcoin.

Of course, no one is literally saying that all investors must make use of it, but in situations where a particular investor is being monitored by the government, then we should expect an idea such as a mixer. Let me give you an example: We know about the current conflict between Russia and Ukraine (though it has lessened). I think it would be ideal for a Russian citizen of great prominence to use a mixing service for any form of trade with someone in Ukraine.

I don't think so.
There are a lot of people who are always interested in privacy for Bitcoin, they are just not so much advertised in news and social media.
New wave of bitcoin developers are coming and I think we are going to see positive changes in this direction soon.
Either that or people who care about privacy will just move to some other coins.

I am certain that Saylor and people like him who are only interested in profit dont care about privacy at all.
In fact they prefer for bitcoin to stay the same and that nothing changes, they could be the ones who could turn bitcoin into ideal surveillance tool with mandatory kyc for all wallets, addresses and transactions.

Yes, again because certain parties will certainly associate the use of Bitcoin mixers with various criminal matters or other things that are considered to be in conflict with the government. Like p=money laundering and also the use of Bictin to fund war activities or other crimes. That's what certain parties relate to, always.

However, for some parties, mixers are really helpful, so again, this is to maintain privacy.

When choosing a mixer, it is required that everyone conducts proper research on how long the particular mixer has been operating. Try to find out from others who have had personal experience (though don't believe everything), and start by mixing smaller amounts (which is where the risk comes in).
I would add seeing the time period that a mixer platform has spent already in the market should not be our main point to tag them as good ones. Because recently many cases have shown that some mixers which was very good in the past and have spent a good long time in the market with positive feedback, and when an offline user come after a long time to use that service again without proper research having a good reputation of that service in mind.

And after using did not get their funds back, why? because they did not check the recent news about them due to which that platform scammed people who already used it and thought they were still functioning properly. I do agree with the tip that we should always use mixer with smaller amounts and if a amount is big, make multiple transactions, or use multiple mixers as currently in the market there are many.

The main problem is, the government would rather shut down mixers than have to look for people who abuse Bitcoin mixer services. This is clearly wrong and contradictory, because I am sure that not all mixer users have the aim of circumventing government regulations relating to money laundering practices. Obviously, this is a very unwise decision, considering that the person at fault is not the mixer, but the individuals who use the mixer for their own illegal purposes.
